Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. It is one of the two main legal systems used throughout the world, the other being civil law. Common law originated in England during the Middle Ages and has since spread to several other countries, including the United States, Canada, India, Australia, and more. It is based on societal customs and recognized by the judgments and decrees of the courts. Common law is flexible and can respond to changes in society, as it allows higher courts to overrule prior decisions without waiting for lawmakers to pass changes in statutes and codes. This has both positive and negative effects on society, as it allows for the evolution of laws to fit the current societal climate, but it can also lead to the marginalization or disempowerment of certain groups if outdated or biased precedents are not overturned.

Common law's flexibility and adaptability
Common law is a body of unwritten laws based on legal precedents established by the courts. It is a system of law that is currently used in several countries, including the US, Canada, India, and Australia, and the UK. It is also practiced in former British colonies such as Hong Kong, New Zealand, India, Pakistan, and Bangladesh.
Common law is flexible and adaptable, as it can respond to changes in society. It does not require lawmakers to pass changes in statutes and codes, which can be a lengthy process or may never happen. In common law systems, higher courts can overrule prior decisions as "bad law" without needing lawmakers to do so. This adaptability is reflected in the Latin legal principle of stare decisis, which translates to "to stand by things decided". In practice, this means that courts and judges need to follow earlier decisions and rulings, but they are not bound by them if they do not reflect contemporary needs or societal changes.
The flexibility of common law allows it to encourage good judgment and adapt to the changing needs of the society it governs. For example, in the case of R (Soma Oil and Gas Ltd) v Director of the SFO [2016] EWHC 2471, the judge considered the economic consequences of a judgment that prioritized legal principle over pragmatism. By drawing on past decisions while remaining adaptable, the judge was able to balance legal principles with practical considerations.
Common law's flexibility is also evident in the interpretation of the Eighth Amendment to the US Constitution, which forbids "cruel and unusual" punishment. The US Supreme Court interpreted this amendment in light of changing social norms, demonstrating the dynamic nature of common law. Similarly, the development of conspiracy law in the 19th century illustrates how common law can adapt to address contemporary problems.
However, the flexibility of common law has its challenges. Past decisions in common law can shape future rulings, which may lead to the marginalization or disempowerment of certain groups. For example, common law in England until the 1970s automatically granted fathers custody of children during divorce, making it difficult for women to leave marriages.

Common law's influence on civil law systems
Common law is a body of unwritten laws based on legal precedents established by the courts. It is a flexible system that can respond to changes in society. It is influenced by institutionalized opinions and interpretations from judicial authorities and public juries. Common law originated in England during the Middle Ages and spread to North America during the 17th and 18th centuries. Today, several countries continue to rely heavily on common law, including the United States, Canada, India, Australia, and Hong Kong.
Civil law, on the other hand, is a more prescriptive system that relies primarily on codes and statutes. It originated in mainland Europe and is centered around a comprehensive code of statutes that outlines procedures and punishments. Civil law systems have clear rules for how judges need to rule on specific disputes. They are influenced by classical Roman law and Justinian law, which provided a model for contracts, rules of procedure, family law, and constitutional law.
One key difference between common law and civil law systems is their approach to precedent. Common law systems heavily emphasize precedent, with judges following earlier decisions and rulings when dealing with similar cases. In contrast, civil law judges tend to give less weight to judicial precedent, and civil law court decisions are not binding in other cases, even if the facts are similar. This means that in civil law systems, judges have more freedom to interpret and apply the law without being constrained by previous rulings.
Another difference lies in the process of changing laws. In a common law system, higher courts can overrule prior decisions without waiting for lawmakers to pass changes in statutes and codes. This flexibility allows common law systems to adapt more quickly to changes in society. In contrast, civil law systems typically require legislative enactments to make changes, which can be a longer process.
The influence of common law on civil law systems can be seen in some countries that were formerly British colonies or protectorates, such as India, Pakistan, Bangladesh, and Hong Kong. These countries' legal systems are largely based on English common law due to the long period of British colonial influence. However, they may also incorporate elements of other legal traditions, resulting in a mixed or hybrid system. For example, Chinese law absorbs some features of the common law system, especially in commercial and international transactions, while also incorporating elements of socialist law.
In conclusion, common law and civil law systems have distinct characteristics, but they can also influence each other, particularly in countries with a complex legal history influenced by multiple traditions. The interplay between these two major legal systems has shaped the legal landscape in many countries and continues to evolve as societies change and adapt.

Common law's impact on societal norms
Common law, also known as case law, is a body of unwritten laws based on legal precedents established by the courts. Common law draws from institutionalised opinions and interpretations from judicial authorities and public juries. It is flexible and can respond to changes in society. Common law is practised in several countries, including the US, Canada, India, Australia, the UK, and Hong Kong.
The impact of common law on societal norms is significant. It has influenced societal customs and has been recognised and enforced by the judgments and decrees of the courts. For example, in the past, common law has led to the unfair marginalisation or disempowerment of certain groups, such as women. In England, common law held that fathers were entitled to custody of the children in cases of divorce, which kept women trapped in marriages.
Common law also affects societal norms by shaping the criteria that juries use to interpret cases. Judges present precedents that influence how juries interpret a case. This can lead to outdated or biased decisions that continue to shape future rulings until societal changes prompt a judicial body to overturn the precedent. This dynamic makes it challenging for marginalised groups to achieve favourable rulings until popular thought or civil legislation changes the interpretation of common law.
Additionally, common law can inspire new legislation. As societal norms evolve, common law can adapt and respond to these changes. For instance, in the early days of the United States, common law was a crucial means of governing society when fewer laws were formally enacted. Common law marriage, which is still legal in many US states, is an example of a common law practice that has influenced societal norms.
In conclusion, common law has a substantial impact on societal norms. It influences societal customs, shapes legal interpretations, and can lead to the marginalisation of certain groups. However, it also provides flexibility and adaptability to changing societal norms, inspiring new legislation. The dynamic between common law and societal norms is complex and ever-evolving, with each influencing the other in a continuous cycle.

Common law's role in marginalizing certain groups
Common law is a body of unwritten laws based on legal precedents established by the courts. It is practised in several countries, including the US, Canada, India, Australia, and the UK. Common law relies on caselaw and legal precedent to guide decisions, rather than codes or statutes.
While common law is flexible and can adapt to societal changes, it has also been criticised for marginalising certain groups. Historically, common law traditions have led to the unfair marginalisation or disempowerment of certain communities. Past decisions continue to shape future rulings until societal changes prompt a judicial body to overturn the precedent. This dynamic makes it challenging for marginalised parties to obtain favourable rulings until popular thought or civil legislation changes the interpretation of common law.
For instance, common law in England, until the 1970s, held that fathers were entitled to child custody upon divorce, effectively trapping women in marriages. Similarly, intestate laws, which are more common among individuals of colour and those with less wealth, may violate equal protection rights by failing to meet the needs of certain sociodemographic groups.
In the United States, between 2020 and 2024, 30 states passed discriminatory laws that adversely affected socially marginalised groups, including people of colour, LGBTQ+ individuals, and women. These laws can have harmful health outcomes and perpetuate stigma, exacerbating discriminatory beliefs and behaviours.
Overall, while common law offers flexibility and adaptability, it has also contributed to the marginalisation of specific groups by perpetuating outdated or biased precedents. It is essential to address these issues and ensure that common law protects and upholds the rights of all individuals in society.

Common law's influence on international law
Common law is a body of unwritten laws based on legal precedents established by the courts. It is a flexible system that can respond to changes in society, as higher courts can overrule prior decisions without waiting for lawmakers to pass changes in statutes and codes. Common law systems are adversarial, with the judge moderating between two opposing parties. They rely on caselaw and legal precedent to guide their decisions, rather than codes and statutes.
The influence of common law on international law is significant, particularly in countries that were formerly British colonies. Common law systems can be found in several countries today, including the US, Canada, India, Australia, Hong Kong, New Zealand, and the UK. The law of India, Pakistan, and Bangladesh is largely based on English common law due to the long period of British colonial influence during the British Raj.
The flexibility of common law allows it to adapt to changing societal norms and values, which can be beneficial in the context of international law. For example, in the United States, the First Amendment protects freedom of the press, which has resulted in weaker protection for freedom of speech compared to other countries. This led to the enforcement of foreign defamation judgments in the SPEECH Act of 2010, demonstrating how common law can shape international law.
Common law's reliance on legal precedent can also influence the interpretation of international law. Judges present precedents that apply to a case, which can significantly impact the criteria used by a jury to interpret it. However, outdated or biased past decisions can continue to shape future rulings until societal changes prompt a judicial body to overturn them. This dynamic between common law and societal change is an important factor in the evolution of international law, as it allows for the adaptation of legal interpretations to reflect changing social values and norms.
Overall, common law has a substantial influence on international law, particularly in countries with a history of British colonial rule. Its flexibility and reliance on legal precedent enable it to adapt to societal changes and shape the interpretation of international law in various parts of the world.

Frequently asked questions
Common law is a body of unwritten laws based on legal precedents established by the courts. It is also known as case law and relies on detailed records of similar situations and statutes.
Common law has been used to govern society for centuries, especially in the early days of the United States. It is flexible and can respond to changes in society. It can also be used to challenge societal norms. For example, common law traditions such as shunning "flamers" and spammers online have influenced the creation of formal legislation criminalizing spam.
Common law marriage, which is legal in many U.S. states, is an example of common law that still exists today. Two persons can become legally married without obtaining a marriage license from the state by meeting the common-law requirements, which usually include publicly declaring that they are married, living together, and co-mingling funds. Another example is the law of India, Pakistan, and Bangladesh, which are largely based on English common law due to the long period of British colonial influence.
